Matlab quadprog

Matlab 中求解二次规划的函数为quadprog，他的用法如下：

x = quadprog(H,f)

x = quadprog(H,f,A,b)

x = quadprog(H,f,A,b,Aeq,beq)

x = quadprog(H,f,A,b,Aeq,beq,lb,ub)

x = quadprog(H,f,A,b,Aeq,beq,lb,ub,x0)

x = quadprog(H,f,A,b,Aeq,beq,lb,ub,x0,options)

x = quadprog(problem)

[x,fval] = quadprog(H,f,...)

[x,fval,exitflag] = quadprog(H,f,...)

[x,fval,exitflag,output] = quadprog(H,f,...)

[x,fval,exitflag,output,lambda] = quadprog(H,f,...)

H,f是把目标函数化成标准形式后得到的实对称矩阵，和列向量。
